Hi Gursharan, I think you need to be more specific. What kind of help do you need?

I need to Implement a code in which i cna extract he image coeficients and can then find an average specific value for every subband.

The find() command will find (tell you the row,column location of)
specific values in your matrix.

And of course you'll need the wavelet toolbox, unless you want to code
everything up yourself.
